# 选择第一个,即为表达量最大值 distinct(ID_REF,.keep_all = T) %>% #去除rowMean这一列 select(-rowMean) %>% #将ID_REF列变成行名 column_to_rownames(var = "ID_REF") 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 好了,常用的数据去重方法先介绍这些,绝对比论文查重简单多了!
arrange(test,Sepal.Length)#从小到大arrange(test,desc(Sepal.Length))#从大到小 2.2 distinct,数据框按照某一列去重复 代码语言:javascript 复制 distinct(test,Species,.keep_all=T) 2.3 mutate,数据框新增一列 代码语言:javascript 复制 mutate(test,new=Sepal.Length*Sepal.Width).###没有赋值,所以修改后的...

One main distinction to keep in mind in this context is that for some properties we really just expect to have a single value, and we are happy to dismiss other values that may be present, while in other cases we expect and want to retain more values. For example, some Wikidata items ...
something more like what is in the vignette to start: fellingdateR offers a set of functions that assist in inferring felling date estimates from dated tree-ring series. Then, describe the problem you want to solve, which I think is estimating when the timber was cut down. Then show the ...
The wide applications of liquid chromatography - mass spectrometry (LC-MS) in untargeted metabolomics demand an easy-to-use, comprehensive computational workflow to support efficient and reproducible data analysis. However, current tools were primarily d
If a column of an r\times n parity check matrix of an [n,n-r]_qR code is treated as a point (in homogeneous coordinates) of \mathrm {PG}(r-1,q) then this parity check matrix defines an (R-1)-saturating n-set in \mathrm {PG}(r-1,q) [5, 11, 13, 19, 21, 23, 27, ...
In the transition rate matrices that we will use here the coalescence configuration corresponds to the last row and column. In the Supplementary Materials we give a general algorithm that can be used to construct the transition rate matrix. Using the transition rate matrix to derive the ...
In general, processing of the compiler options is from left to right, allowing selective overriding of macro options (options that include other options). This rule does not apply to linker options. However, some options, -I, -L, and -R for example, accumulate values rather than override pr...
We explore this function in the context of the several distinct gene expression-related situations presented above, describing situations when certain collapsing methods are advantageous. For example, we find that in most microarray experiments performed on brain tissue it is best to choose the probe ...
